RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Andy Grover 2012-11-21 20:02:06 UTC 
+++ This bug was initially created as a clone of Bug #878711 +++

Description of problem:

Can we support to create the wwn alias which is the general function of the storage array.

It will benefit the users that they don't have to always remember which wwn is belong which initiator. 

The following is the layout of netapp wwn alias ( they call it igoup ).
It can assign multiple WWNs to one igroup.

Comment 1 Andy Grover 2012-11-21 20:04:04 UTC 
Initiators should be groupable by iqn (for iscsi) or wwn (for fc/fcoe) so they can have ACLs managed for all of them in the group at once.
Comment 2 Xiaowei Li 2012-11-23 05:59:24 UTC 
Another request is to set the auto_add_mapped_luns to false.

Usually the users need to do lun mapping manually.

set the default auto_add_mapped_luns to false.
Comment 5 Andy Grover 2013-07-03 18:31:02 UTC 
implemented using tag and untag commands under 'acls' node.
